PURPOSE: A bush structure of a suspension arm is provided to improve the adjustment performance of a vehicle by optimizing the hardness of a suspension arm bush. CONSTITUTION: A bush structure of a suspension arm comprises a cylindrical inner pipe(100), a cylindrical outer pipe(200), and a buffer member(300). The outer pipe covers the outer circumference of the inner pipe. The buffer member comprises an inner buffer unit(310) and an outer buffer unit(320) and is equipped between the inner and outer pipes. The inner buffer covers the inner pipe and is made of a low hardness synthetic resin. The outer buffer unit is equipped between the inner and outer buffer units and is made of high hardness synthetic resin. |
